Product Description

Overview

Compared to semiconductor temperature sensors, thermocouples have a wide working range, and do not need any external excitation power. They are cost effective and interchangeable. In some high temperature application, they may be the only practical choice with a reasonable price. Signal conditioning is the most tricky part for thermocouple temperature sensors, it deals with micro volts amplification and the cold junction compensation. Thanks to the MAX6675/MAX31855, all the signal conditioning had already been done inside the chip, and the amplified analog voltage is digitized and accessible to external MCU via SPI interface.
